I could have been more clear, this is exactly what I meant. If so, the answer is The average number of processes waiting to use the processor Top, for example, shows the average over the last 5, 10, and 15 minutes. Basically, if your load average is below 1, it means processes aren't waiting to use the comptuer, if it goes above one, it means that the machine is busy enough that at any point in time, x number of processes are waiting to execute (on average) - where x is the load average reported. It's one of many indicators of how busy your box is. Keep in mind that it doesn't mean that processes are waiting to work - i.e. the processes are still executing within that average second. But a load average of 3 means that in order for a process to execute, there are three other processes that are suspended. Of course, the scheduler will rotate those in so they all get equal CPU usage ... but in order to rotate the next process in, the currently executing one gets suspended. Outstanding! That's exactly what I was looking for.

Load
Does anybody have a nice definition of the UNIX term load ? I have a gut-level idea of what it is, but nothing that I can pass on to non-UNIX people. Any help? -- David Olbersen iGuard Engineer 11415 West Bernardo Court San Diego, CA 92127 1-858-676-2277 x2152 ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Help with IDE RAID
Here's the history: I installed a Promise TX2000 IDE RAID along with 2 drives. Booted into the BIOS of the TX2000 and defined a RAID-1 array using both drives. Then, due to circumstances, I had to take out the card and replace it with a plain IDE controller (Promise Ultra 100). Now when I boot I see the following in dmesg: ===snip!=== atapci1: Promise ATA100 controller port 0xef00-0xef3f,0xefa4-0xefa7,0xefa8-0xefaf,0xeff0-0xeff3,0xefe0-0xefe7 mem 0xffac-0xffad irq 11 at device 20.0 on pci0 ===snip!=== ar0: 117301MB ATA RAID1 array [14953/255/63] status: DEGRADED subdisks: 0 FREE ad6: 117800MB IC35L120AVV207-0 [239340/16/63] at ata3-master UDMA100 1 READY ad4: 117800MB IC35L120AVV207-0 [239340/16/63] at ata2-master UDMA100 ===snip!=== So it looks like I have an array (ar0) even though I don't have the RAID controller any more! `atacontrol list` gives the following: ATA channel 0: Master: no device present Slave: no device present ATA channel 1: Master: no device present Slave: no device present ATA channel 2: Master: ad4 IC35L120AVV207-0/V24OA63A ATA/ATAPI rev 6 Slave: no device present ATA channel 3: Master: ad6 IC35L120AVV207-0/V24OA63A ATA/ATAPI rev 6 Slave: no device present So I tried `atacontrol detach 3`. Then rebooted. The dmesg about above is from after that boot. The array is still there, but degraded. I'd like to just get rid of it and have my two drives (ad4 and ad6) to use with vinum. This machine is running 4.5-STABLE #1, any suggestions? -- David Olbersen iGuard Engineer 11415 West Bernardo Court San Diego, CA 92127 1-858-676-2277 x2152 ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
